Description

Technical Field

[0001] This utility model relates to the field of color masterbatch equipment technology, and in particular to a screening device for color masterbatch production. Background Technology

[0002] Color masterbatch, also known as color masterbatch, is a new type of colorant specifically for polymer materials. It is cylindrical in shape and is also called pigment preparation. During the production of color masterbatch, the masterbatch strips need to be granulated. However, problems such as incomplete cutting, uneven cuts, leftover scraps, and high-temperature adhesion occur during the granulation process, resulting in color masterbatch particles of varying sizes. Therefore, it is necessary to screen the color masterbatch.

[0003] Patent No. ZL 202223007188.1 discloses a screening device for color masterbatch. Through the back-and-forth movement of a first, second, and third screening component, and the gravity of the color masterbatch itself, the primary, secondary, and tertiary screening mechanisms sequentially screen the color masterbatch from small to large size, ensuring stable screening and better efficiency. However, the solution mentioned in the aforementioned patent relies on three independent screening components, resulting in a large space requirement, high equipment cost, and difficulty in controlling the amount of color masterbatch fed. Furthermore, when there is significant stacking between color masterbatches, the upper layer cannot be effectively screened. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a screening device for the production of color masterbatch.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screening device for the production of color masterbatch is characterized in that it includes a feeding mechanism, a screening mechanism and a base installed sequentially from top to bottom, as well as a vibration mechanism connected to the screening mechanism.

[0007] The screening mechanism includes several screening components stacked on top of each other. Each screening component includes overlapping screens and receiving plates, as well as a frame surrounding the screens and receiving plates. The receiving plate has a discharge hole on the side away from the screen. The screen surface is evenly distributed with several through-holes. The diameter of the screen holes in each layer of screening components decreases from top to bottom.

[0008] The feeding mechanism includes a hopper located above the top screening component, an inlet and an outlet located on the top and bottom sides of the hopper, and a rotatable distribution plate located inside the hopper. The hopper is located on the side of the screen away from the receiving plate. The distribution plate divides the inside of the hopper into several material troughs. The inlet and outlet are connected to the inside of the hopper and correspond to the positions of the material troughs.

[0009] Preferably, the hopper is a horizontally arranged cylindrical structure, and is coaxially provided with a rotating shaft that drives the material distribution plate to rotate. The rotating shaft is connected to a material distribution motor, and the material distribution plate is sleeved on the outside of the rotating shaft.

[0010] Preferably, the material distribution plate has a cross-shaped structure, with the center of the material distribution plate coaxially connected to the rotating shaft, and the outer side of the material distribution plate extending towards the inner wall of the hopper.

[0011] Preferably, the screening mechanism includes a column integrally connected with several screening components, and an ear with a screw hole is provided on the outer side of the frame. The column is inserted into the screw hole and is rotatably connected to the screw hole.

[0012] Preferably, the bottom screen in the plurality of screening components is a flat plate structure, and its surface is provided with a brush for cleaning, and a moving component for driving the brush to move towards the receiving plate.

[0013] Preferably, the frame includes a straight baffle and a V-shaped plate that are connected to each other, the screen is embedded inside the straight baffle, the receiving plate is closed at the bottom of the V-shaped plate, and the discharge hole is set relative to the end of the V-shaped plate.

[0014] Preferably, the straight baffle and the V-shaped plate form an inclined angle, the inclination angles between the screening components of each layer are not the same, and the discharge holes are misaligned.

[0015] Preferably, the vibration mechanism is located above the topmost screening component and includes a fixed base connected to the frame and a vibration motor inclinedly mounted on the fixed base.

[0016] Preferably, the base is located below the bottommost screening component and includes a shock-absorbing spring connected to the frame and a support frame located below the shock-absorbing spring.

[0017] This utility model has the following beneficial effects:

[0018] This invention, by setting up a feeding mechanism and a screening mechanism, allows for the screening of color masterbatch. When color masterbatch needs to be screened, it is poured into the hopper through the feed inlet. A separating plate divides the color masterbatch, and as the separating plate rotates, the color masterbatch sequentially fills each trough. The color masterbatch in the trough falls into the screening component through the discharge outlet, effectively controlling the amount of color masterbatch fed and preventing excessive accumulation. Then, under the action of the vibration mechanism, the multi-layer screening component works synchronously, with the screens reciprocating and screening the color masterbatch. Color masterbatch larger than the screen aperture remains on the current screen layer, while color masterbatch smaller than the screen aperture falls into the next screen layer. Finally, the color masterbatch located on each screen layer moves towards the receiving plate and is discharged through its respective discharge hole, achieving a step-by-step screening effect. Because the screening component is a multi-layered vertical distribution driven by the same vibration mechanism, it effectively saves equipment costs and reduces space size.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1 to 4 One embodiment provided by this utility model:

[0026] A screening device for the production of color masterbatch includes a feeding mechanism, a screening mechanism, and a base installed sequentially from top to bottom, as well as a vibration mechanism connected to the screening mechanism. The screening mechanism includes several layered screening components, each including an overlapping screen 1 and a receiving plate 2, and a frame 3 surrounding the screen 1 and the receiving plate 2. The receiving plate 2 has a discharge hole 4 on the side away from the screen 1. The surface of the screen 1 is evenly distributed with several through-holes 5, and the diameter of the screen holes 5 in each layer of screening components decreases sequentially from top to bottom. The feeding mechanism includes a hopper 6 located above the top screening component, an inlet 7 and an outlet 8 respectively located on the top and bottom sides of the hopper 6, and a distribution plate 9 rotatably located inside the hopper 6. The hopper 6 is located on the side of the screen 1 away from the receiving plate 2. The distribution plate 9 divides the inside of the hopper 6 into several troughs. The inlet 7 and the outlet 8 are respectively connected to the inside of the hopper 6 and correspond to the positions of the troughs.

[0027] The screening equipment is used in the production of color masterbatch to achieve step-by-step screening of color masterbatch size. The feeding mechanism, screening mechanism, and base are installed sequentially from top to bottom, with the feeding mechanism located above the screening mechanism and the base located below the screening mechanism. The vibration mechanism is connected to the screening mechanism to provide vibration force to the screening mechanism.

[0028] The screening mechanism has a multi-layer structure, with several screening components vertically stacked. Each screening component includes a screen 1, a receiving plate 2, and a frame 3. The screen 1 and the receiving plate 2 overlap, or the screen 1 can be inclined downwards towards the receiving plate 2. The frame 3 surrounds the outside of the screen 1 and the receiving plate 2, blocking the masterbatch located above the screen 1 and the receiving plate 2. The receiving plate 2 is a flat plate structure, with its beginning end connected to the screen 1. The discharge hole 4 is located at the end of the receiving plate 2, positioned relative to the side furthest from the screen 1, and is connected to the outside. The screen 1 has a mesh structure, with several screen holes 5 evenly distributed on its surface, forming a continuous structure. After the masterbatch enters the screen 1, it is screened by the screen holes 5 under the action of vibration. The screened masterbatch enters the receiving plate 2 and is discharged from the discharge hole 4. The aperture diameter of the sieve holes 5 in each screening component decreases sequentially from top to bottom. The screening mechanism can consist of three layers of screening components. The aperture diameters of the sieve holes 5 in the upper, middle, and lower screening components are sizes A, B, and C, respectively, where size A is larger than size B, which is larger than size C. If the masterbatch is larger than the aperture diameter 5 of its layer, it remains in that layer's screening component. If the masterbatch is smaller than the aperture diameter 5, it falls into the next layer's screening component, achieving a step-by-step screening effect.

[0029] The hopper 6 is located above the top-level screening assembly, on the side away from the receiving plate 2 relative to the screen 1. The inlet 7 is located at the top of the hopper 6 and communicates with the interior of the hopper 6. The outlet 8 is located at the bottom of the hopper 6 and communicates with the interior of the hopper 6. The distributor plate 9 is located inside the hopper 6, rotatably connected to the hopper 6, and divides the interior of the hopper 6 into several troughs. The troughs correspond to the positions of the inlet 7 and the outlet 8. When masterbatch is poured in from the inlet 7, it fills one trough. As the distributor plate 9 rotates, the positions of the troughs change, and the masterbatch fills the other troughs sequentially. When the trough aligns with the outlet 8, the masterbatch in the trough is poured into the screen 1 from the outlet 8, thus controlling the amount of masterbatch fed in.

[0030] This invention, by setting up a feeding mechanism and a screening mechanism, allows for the screening of color masterbatch. When color masterbatch needs to be screened, it is poured into the hopper 6 through the feed inlet 7. The distribution plate 9 separates the color masterbatch, and as the distribution plate 9 rotates, the color masterbatch sequentially fills each hopper. The color masterbatch in the hopper falls into the screening component through the discharge port 8, effectively controlling the amount of color masterbatch fed and avoiding excessive accumulation. Then, under the action of the vibration mechanism, the multi-layer screening component works synchronously. The screen 1 moves back and forth, screening the color masterbatch. Color masterbatch larger than the aperture 5 of the screen remains on the current layer of screen 1, while color masterbatch smaller than the aperture 5 falls into the next layer of screen 1. Finally, the color masterbatch located on each layer of screen 1 moves towards the receiving plate 2 and is discharged through its respective discharge port 4, achieving a step-by-step screening effect. Because the screening component is a multi-layered vertical distribution driven by the same vibration mechanism, it effectively saves equipment costs and reduces space size.

[0031] In this embodiment, preferably, the hopper 6 is a horizontally arranged cylindrical structure, and is coaxially provided with a rotating shaft 10 that drives the material distribution plate 9 to rotate. The rotating shaft 10 is connected to a material distribution motor 11, and the material distribution plate 9 is sleeved on the outside of the rotating shaft 10.

[0032] The hopper 6 is horizontally positioned and has a cylindrical structure. A rotating shaft 10 is inserted inside the hopper 6 and coaxially aligned with it, used to drive the distribution plate 9 to rotate. A distribution motor 11 is connected to one end of the rotating shaft 10, and the distribution plate 9 is sleeved on the outside of the rotating shaft 10. Under the action of the distribution motor 11, the rotating shaft 10 drives the distribution plate 9 to rotate. During the rotation of the distribution plate 9, the positions of the various material troughs switch, allowing the masterbatch to fill the troughs sequentially.

[0033] In this embodiment, preferably, the material distribution plate 9 has a cross-shaped structure, the center of the material distribution plate 9 is coaxially connected with the rotating shaft 10, and the outer side of the material distribution plate 9 extends towards the inner wall of the hopper 6.

[0034] The material distribution plate 9 is horizontally arranged in a cross shape, including four centrally symmetrical support plates. The rotating shaft 10 is inserted into the center of the material distribution plate 9 and coaxially connected with the material distribution plate 9. The outer side of the support plates extends into the inner wall of the hopper 6, dividing the inside of the hopper 6 into four material troughs of equal capacity.

[0035] In this embodiment, preferably, the screening mechanism includes a column 12 integrally connected with several screening components, and an ear 13 with a screw hole is provided on the outer side of the frame 3. The column 12 is inserted into the screw hole and rotatably connected to the screw hole.

[0036] The column 12 is vertically arranged and has a stud-like structure. Several screening components are integrally connected through the column 12. The ears 13 are evenly distributed on the outside of the frame 3 and have through screw holes. The column 12 is inserted into the screw holes and is rotatably connected to the screw holes to lock the frame 3 of each screening component, so that the multi-layer screening components are driven by the same vibration mechanism.

[0037] In this embodiment, preferably, the bottom screen 1 among the screening components is a flat plate structure, and its surface is provided with a brush for cleaning, as well as a moving component that drives the brush to move towards the receiving plate 2.

[0038] The bottom layer of screen 1 is a flat plate structure without screen holes 5. After the masterbatch passes through multiple layers of screen 1, the debris and powder mixed with the masterbatch fall into the bottom layer of screen 1. This screening component is used to collect waste and discharge it uniformly. The brush is located above screen 1 and is set in close contact with the surface of screen 1. The moving component is connected to the brush drive. Driven by the moving component, the brush moves towards the receiving plate 2 and cleans the surface of screen 1 to remove debris and powder.

[0039] In this embodiment, preferably, the frame 3 includes a straight baffle 14 and a V-shaped plate 15 that are connected to each other. The screen 1 is embedded in the inner side of the straight baffle 14, the receiving plate 2 is closed at the bottom of the V-shaped plate 15, and the discharge hole 4 is provided relative to the end of the V-shaped plate 15.

[0040] The straight baffle 14 is horizontally positioned, and the V-shaped plate 15 has a V-shaped structure. Two straight baffles 14 and one V-shaped plate 15 are connected to each other, with the beginning of the V-shaped plate 15 connected to the straight baffle 14. The discharge hole 4 is positioned relative to the end of the V-shaped plate 15. The screen 1 is embedded inside the straight baffle 14, and the receiving plate 2 is closed at the bottom of the V-shaped plate 15. The masterbatch vibrates and advances on the surface of the screen 1, enters the receiving plate 2 from the screen 1, and converges towards the discharge hole 4 at the end of the V-shaped plate 15 under the guidance of the V-shaped plate 15.

[0041] In this embodiment, preferably, the straight baffle 14 and the V-shaped plate 15 are inclined at an angle, the inclination angles between the screening components of each layer are not the same, and the discharge holes 4 are misaligned.

[0042] The straight baffle 14 and the V-shaped plate 15 form an obtuse angle, which facilitates the convergence of the masterbatch towards the discharge hole 4. The inclination angles between the screening components are not the same. The screening mechanism may include three screening components, with the inclination angles of the V-shaped plate 15 in the upper, middle, and lower screening components being 105 degrees, 120 degrees, and 135 degrees, respectively. This allows the discharge holes 4 to be staggered between the screening components, resulting in a more rational arrangement of the discharge holes 4.

[0043] In this embodiment, preferably, the vibration mechanism is located above the topmost screening component, including a fixed base 16 connected to the frame 3, and a vibration motor 17 inclinedly disposed on the fixed base 16.

[0044] The vibration mechanism is located above the top screening component, which reduces the overall height of the screening equipment and makes it easier to pour the masterbatch into the hopper 6. The fixed base 16 is located above the frame 3 and is fixedly connected to the frame 3. The fixed base 16 includes an inclined mounting surface. The vibration motor 17 is inclinedly mounted on the mounting surface. In this installation mode, when the vibration motor 17 is started, the masterbatch can vibrate forward and move from the screen 1 towards the receiving plate 2.

[0045] In this embodiment, preferably, the base is located below the bottommost screening component and includes a shock-absorbing spring 18 connected to the frame 3 and a support frame 19 located below the shock-absorbing spring 18.

[0046] The base is located below the bottom screening components, which can alleviate the vibration effect of the vibration mechanism on the ground and reduce the noise of the screening equipment. The shock-absorbing springs 18 are symmetrically arranged below the frame 3, and are vertically installed and fixedly connected to the frame 3. The support frame 19 is located below the shock-absorbing springs 18 and has multiple support feet evenly distributed.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
